Yes I did.
The reason I send to this list also is that in make.conf manual says:
CFLAGS (str) Controls the compiler setting when compiling C code.
Optimization levels other than -O and -O2 are not
sup- ported.
That means that -O2 should be supported in FreeBSD. And now it happens
to produce bad code.
GCC people think that this should be fixed in gcc 4.3.
I have not yet installed and verified that. However I tried the code
with linux installation with gcc 4.1.2 and it was ok.
As I don't known if gcc has some maintaining done in FreeBSD tree by
patching or just by integrating the next snapshot from time to time.
So I just though to report it in case that maintainers of
FreeBSD version of gcc might want to take a look at this.
